Top 12 Best Online Documentation Software & Tools in 2024

Online Documentation Software

Having explored a variety of documentation software and online documentation tools, I’ve learned how these tools can be used to streamline workflows, enhance collaboration, and secure data integrity across projects and teams. 

They can address challenges like organizing vast amounts of information, ensuring consistency in documentation standards, and facilitating real-time collaboration across global teams to make critical information readily accessible.

Employees spend up to 20% of their workweek looking for information. Also, 56% of customers visit a company’s website before calling customer support. So, the need for online documentation is evident for both internal teams and customers. 

In this blog, I will share my top 12 documentation software and online documentation tools to create online documentation. Let’s start with a quick summary of my top three. 

Best online documentation software Best For Pricing
ProProfs Knowledge Base Creating online documentation, manuals, help sites, and private knowledge bases Forever free plan for up to 25 articles with all premium features. Paid plan starts at $49/author/month

Now, before discussing the tools, let’s look into some basics. 

What Is Online Documentation Software? 

Online documentation software refers to cloud-based tools or web applications designed to create, store, manage, and share digital documents and manuals. 

Unlike traditional documentation methods that rely on physical documents or localized digital files, online documentation software uses the internet to offer real-time access, team collaboration, and distribution of information. 

They help you create public and private documentation for your customers and employees. It comprises powerful features that assist you at every content creation step, from authoring and editing to designing and publishing. 

You can kickstart the journey of document creation using pre-designed templates and encourage collaborative authoring by defining the roles and responsibilities of each user. Online documentation tools also support complete site customization, so you can build documents that blend well with your brand.

Robust online documentation tools offer intuitive content creation and management features, strong collaboration and version control capabilities, and flexible access controls to ensure information security. 

Here are my top three all-round tools.

With ProProfs Knowledge Base, you can jumpstart your documentation creation process using the pre-designed templates and AI-powered, MS Word-like text editor.

Option #2 – Whatfix

With Whatfix, you can create step-by-step guides, tooltips, and walkthroughs that integrate seamlessly with your software environment. 

Its analytics also offer insights into how users interact with the documentation, enabling continuous improvement based on user behavior and feedback. 

Option #3 – Document360

Document360 offers a Markdown editor for easy content creation and version control to manage edits and updates efficiently. 

It supports a hierarchical structure for organizing articles, making navigating and retrieving information simple.

Its powerful search functionality, with auto-suggest and search analytics, further enhances the user experience by making it easier to locate specific topics or instructions within the vast pool of available content.

2. Whatfix – Best for Creating In-App Application-Support Content

Whatfix lets you build interactive and contextual help within your applications, enhancing user experience and aiding in software adoption. By integrating directly into the application interface, it guides users through tasks with real-time, step-by-step instructions, effectively reducing confusion and increasing productivity.

For me, its standout feature is its ‘Flows, ‘ which enables the creation of interactive walkthroughs that guide users through various processes within the application. These Flows are particularly effective because they are dynamic and context-aware, meaning they adapt to the user’s actions and provide guidance based on the current context within the application. 

The platform also offers ‘Self-Help Menus’ and ‘Task Lists’, essential features for creating a comprehensive in-app knowledge base. The Self-Help Menu acts as a centralized repository of Flows, FAQs, and articles that users can access at any point, offering instant assistance without the need to leave the application. 

What you will like: 

What you may not like:

  • The content creation platform could be overwhelming until it is mastered
  • The ability to identify CSS selector options for using WhatFix within Salesforce would have been better

3. Document360 – Best for Creating AI-Powered Online Documentation

My team has used it for its version control and rollback features, which ensure that changes are tracked meticulously, enabling authors to revert to previous versions if necessary, thus safeguarding the integrity of the documentation over time. It facilitates content organization through its ‘Category Manager,’ which allows for a hierarchical structure, making it straightforward for users to navigate and find the information they need quickly. 

Its predictive search and search analytics ensure that users can efficiently locate specific topics or answers within the knowledge base. It provides a customizable and branded space for documentation hosting – you can tailor the look and feel of their portal to match their brand identity, enhancing the user experience.

As edits are made, changes are instantly visible to all contributors, ensuring everyone is constantly working with the most current information.

A free version is available for up to 50 items. Paid plan starts at $5/user/month.

5. Scribe – Best for Generating Visual How-to Guides

Scribehow’s visual how-to guides allow users to effortlessly create step-by-step tutorials and guides, capturing actions as they happen on their screen. Including screenshots, annotated images, and concise instructions enhances comprehension and retention, enabling a smoother learning curve for new software or procedures.

My favorite is its ‘Real-Time Capture’ feature, which tracks the user’s actions in real-time, automatically generating documentation for each process step – as a user navigates through a task, it captures every click and keystroke, translating these actions into a comprehensive, easy-to-understand guide.

Its built-in templates and themes have also been a boon, enabling us to maintain consistency in our documentation’s look and feel without extensive customization work.

One of the most compelling features of the platform is its library management system, which lets us efficiently organize and reuse multimedia content like images, videos, and documents. This streamlines the documentation process and ensures that our content is rich and engaging, making complex IT concepts easier for our users to understand.

What you will like:

  • Lets users publish to multiple formats without additional formatting or tools

ClickHelp allows users to provide targeted help to users based on their context within the software or application. By embedding context-sensitive help directly into the interface, users can access relevant information at the point of need, enhancing user experience and reducing support queries.

I have listed it for its powerful content reuse features that ensure consistent, correct, and top-quality content. This includes importing content from formats like Microsoft Word, HTML, RTF, CHM, ODT, and more and exporting to formats such as CHM, HTML5 Web Help, PDF, DOCX, and others.

KnowledgeOwl aims to streamline information access for customer service representatives by enabling a centralized repository where call center agents can quickly find answers to customer queries, standard operating procedures, and product information.

I like it for its search functionality, which is designed to help users quickly find the information they need. It employs intelligent search algorithms prioritizing relevance and accuracy for call center agents seeking information during a call or an end-user navigating a self-service knowledge base.

The platform also allows you to tailor your knowledge bases to reflect your brand identity, including custom URLs, logos, color schemes, and layout designs, which not only enhance the visual appeal of the documentation but also provide a seamless user experience that aligns with the company’s overall digital presence.

Paid plan starts at $100/month for all the premium features.

9. Confluence – Best for Team Collaboration

Confluence enables a highly collaborative environment by providing a centralized workspace where team members can collaborate on projects, share ideas, and document progress. It offers templates for various types of teams and projects. It simplifies the process of creating project plans with text, tables, images, timelines, code, and more, all within a unified platform.

My favorite is its extensive reporting capabilities, which provide valuable insights into project vitality and team progress, allowing teams to track tasks, monitor progress, and optimize efficiency. 

Confluence’s space and page permissions allow managing who can view or contribute to different parts of your documentation.

10. Notion – Best for Internal Wikis for Team Sharing Informal Knowledge

Notion allows you to create centralized repositories where team members can store, organize, and access all forms of knowledge — from project overviews and company policies to how-to guides and FAQs. The ability to effortlessly share informal knowledge enhances team collaboration. It ensures that valuable insights and information are preserved and easily accessible.

I like how its ‘Drag-and-Drop Interface’ and ‘Rich Content Blocks let users create and customize their documentation with an intuitive drag-and-drop interface, making organizing content that best suits their needs simple. It supports a variety of content blocks — text, images, videos, code snippets, and more — allowing for the creation of dynamic and interactive documents. 

The platform’s collaborative editing allows multiple users to simultaneously work on the same document. Real-time updates and the ability to leave comments facilitate seamless collaboration among team members, enhancing the documentation process.

11. Read the Docs – Best for Open Source Documentation

Read the Docs’ integration with version control systems like GitHub, Bitbucket, or GitLab helps it automatically generate documentation each time code is committed to the repository. This seamless synchronization ensures that the documentation remains up-to-date with the latest code changes, eliminating the need for manual updates. 

Its version control enables the management of documentation across different versions of the software. This is particularly useful for projects that maintain multiple active versions simultaneously.

Sphinx’s ‘Automatic Indices & Code Handling’ automatically generates indices and cross-references, making navigation through documentation smoother and more intuitive. It is particularly beneficial for technical documentation that includes numerous functions, classes, or modules, as it organizes and links content so that users can easily understand the structure and find the information they need. 

Also, I found Sphinx’s handling of code snippets exemplary; it can highlight syntax in various programming languages, enhancing readability and comprehension for developers.
